BUTTON.

Application filed March 3, 1911. Serial No. 612,151.

Specification of Letters Patent.

Patented May 28,1912.

- ject of the Emperor of Germany, and MAX VILLE BERNSTEIN, a British subject, both residing in the city of Toronto, in the county of York and Province of Ontario, Canada, have invented certain new and useful Improvements in Buttons; and we hereby declare that the following is a full, clear, and exact description of thesame.

Our invention relates to an improved button comprising a shank member having a hollow stem with a concave but-ton seat adapted to receive the button back, as well as a'ooupling member to which said back may be readily attached. The said coupling member is provided with-a perforation and a bar portion registering with the hollow stem portion of the shank, and enabling the said coupling member to be sewed to the cloth through the hollow stem portion of the shank. Further, the back portion of the button is provided with a projecting member adapted to fit intoand to be locked with the said coupling member after the latter is sewed to the cloth, all as will-be more fully hereinafter disclosed.

In order that the invention may be better understood, reference is had to the following description taken in connection with the accompanying drawings forming a part of this specification, in which- Figure 1 is a perspective view of the shank portion of the button with the coupling member removed; Fig. 2 is a perspective view of the coupling member which is adapted to fit into the concave shank member shown in Fig. 1; Fig.3 is a perspective view of the button back adapted to fit over the shank portion of the button and provided with a projecting coupling member adapted to fit into the hollow coupling member illustrated in Fig. 2; Fig. 4 is a perspective view showing the shank member and its hollow coupling memberv in place ready to be sewed tothe cloth before the button back shown in Fig. 3, isattached thereto; Fig. 5 is an inverted perspective View of the completed button, showing the parts illustrated in Figs. 3 and 4: when secured together; Fig. 6 is a sectional view on a reduced scale of the completed button when assembled; and, Fig. 7 is a sectional view of the button back and coupling member provided with an interlocking means involving abayonet slot.

Like characters designate like parts in all the views. Y

The button shank member a, best illustrated in Figs. 1 and 4, comprises a hollow stem a through which the sewing threads may pass, and is also provided with the hollow concave button seat a adapted to receive the hollow coupling member (1,

.shown in Fig. 2, and to have the perforation a of the latter register with the hollow of the stem a, as best illustrated in Fig. 4.

When the holes or perforations e of the coupling member 0? are properly alined with the bore of the stem a, as illustrated, the said coupling member (Z together with the shank member a is firmly sewed to the cloth by passing threads through the holes 6 over the bar portion, separating said holes, as will be readily understood. After the hollow stem portion a has been correctly positioned on the material, the coupling member d centrally placed on the button seat a and the threads passed through the holes e and the cloth a sufiicient number of times to cause the shank member a and the hollow coupling member (Z to be securely attached to the garment, the button back 0 provided with the projecting attaching member f, is then brought into position, and the said attaching or coupling member f is fitted into the hollow coupling member d and secured in place, as by the male and female threads illustrated. The button back 0 is preferably convex on its under side, so that it fits the hollow portion of the concave buttonseat a, which is occupied .by the hollow coupling member cl. The button back 0 may be provided with any style of button face 9, and by this means of attaching the buttons to the garments, the button faces may therefore be quickly changed without having to resew the shanks to the material. In other Words, cloth, bone, metal, and other buttons, may. be inter-changed and used on the same shanks. By the use of shanks of this description, we are able to attach buttons to the garments so that they are uniformly spaced from the material, and by means of the hollow stems, we are able to protect the button holes from wearing on the threads that attach the but tons, and at the same time, we also prevent therefore, do not wish to be limited to the above disclosure, except as may be required by the claims.

hat we claim is 1. In a button, the combination of a shank member provided with an integral hollow stem portion and a concave button seat; a coupling member provided with a perforation adapted to register with the bore. of said hollow stem and with means by which said member maybe secured to the cloth through said stem; and a button back provided with a face portion adapted to fit said concave button seat, and having a projecting portion adapted to inter-lock with said coupling member, substantially as described.

2. In a button, the combination of a shank member comprising an integral hollow stem portion through which threads may pass and a concave button seat; a hollow cupshaped coupling member adapted to rest on 35 said button seat and having a locking member, also said coupling member provided with a perforated bottom by means of which it may be secured to the cloth through said hollow stem portion; and a button back 40 adapted to fit said button seat and having a projecting portion provided with locking means adapted to engage said locking member with which said coupling member is provided, substantially as described.
